Re: LG 32L46 No Turning On

Quick update still not found camera will use phone.
By chance found the exact board all numbers matched on fleabay good bargain price £6 lol @ £5pp so great.

Before plugging the (new used board) into Tv i check it against the faulty board, found it to be shorted to ground around those little capacitors where they are seated 3 in a row across the board if thats the correct terminology. So not sure if replacing the mentioned fuses above would of fixed that issue.

Cut to the chase tv is now on working to a certain degree?...

I replaced those 2 bad caps the led to front functions correctly now Green Tv is On, Red its in Standby.

Also did bit of reflow work on what I wasn't sure if could be problems around transformers legs or anything with brown residue.

So I kinda sure the power supply side is ok?

I noticed on switching on a...

This is the second set, not to confuse things, the first set is working fine.

Try to read from the service manual got as far as Is a DC voltage of approx. 400V applied to both ends of C7129?

So far the readings on CN7201

1. 13.32/45 On pressing the power on button
2. 13.32/45 On pressing the power on button
3. 13.32/45 On pressing the power on button
4. 13.32/46 On pressing the power on button
5. GND 1.0mv
6. GND 1.0mv
7. GND 0v
8. GND 0v
9. Ac-Det 3.30v...

Re: Sharp LC32D44E-BK Stuck in standby mode

It does not turn on, 1 sec of green led then back to red again. Think I seen somewhere on 1 the post about 1 sec of green is inverter?

Cant remember if I heard a click or not was just giving it a quick look over.

I did remove the PSU, area around a few FET's look brown, those by the heatsinks.

Will update with few photos tomorrow, and any findings, most def will have a hundred questions to ask also.

Re: Samsung LE40M87BDX\XEU

Thanx Tom66 for your input, replaced the AV mainboard today, so far aint heard nothing back from the person.

Had a little scare at first, plugged in the AV board connected it up, it was saying no input signal, & something about HDMI STB. Thought the AV board was faulty.

Did a reset and all come good

Many Thanx for all those that's help

Re: Samsung LE37M86 - Flickering green artifacts on screen

That's the same mainboard im replacing on a Sammy, LE40M87BDX, those green lines was the same effect I got when heated a certain part of the mainboard.

It was causing the set to cut out & resetting. Cant give a accurate part location on the board at the moment, I have a look later.

Re: Samsung LE40M87BDX\XEU

Think this is the correct one, will call the seller tommorow.

Says its this BN41-00813B-MP1.0 for LE40M87BDX

Then further down the page its says BN41-00813E-MP1.0.

It looks the same, all connect ports look in the same spot.
